Compositions from liquid conjugated diene polymers

Claim 1

A METHOD OF MAKING A POLYMERIC PRODUCT WHICH COMPRISES MIXING A FIRST POLYMER OF A CONJUGATED DIENE HAVING 4 TO 8 CARBON ATOMS PER MOLECULE, SAID FIRST POLYMER HAVING A MOLECULAR WEIGHT IN THE RANGE OF 1000 TO 20,000 AND AT LEAST 2 TERMINALLY REACTIVE GROUPS PER MOLECULE, SAID TERMINAL GROUPS CONTAINING AT LEAST ONE REACTIVE ELEMENT BONDING SELECTED FROM THE GROUP CONSISTING OF O-H, S-H, N-H, S-X, OC-X, SC-X, RC-X, C=O, C=S AND C$N WHEREIN X IS HALOGEN AND R IS SELECTED FROM THE GROUP CONSISTING OF CARBONYL, THIONO, ETHENYLENE AND A CARBON IN AN AROMATIC RING, WITH A PLASTICIZING AMOUNT OF SECOND HOMOPOLYMER OF 1,3-BUTADIENE, SAID SECOND POLYMER HAVING A VISCOSITY IN THE RANGE OF ABOUT 10 TO 500 POISES AT 77*F. AND UP TO 15 PERCENT OF ITS UNSATURATION IN THE VINYL FORM, UP TO 55 PERCENT OF ITS TRANS FORM, AND FORM 35 TO 85 PERCENT OF ITS UNSATURATION IN THE CIS FORM, AND CURING THE RESULTING MIXTURE BY REACTING SAID TERMINALLY REACTIVE GROUPS OF SAID FIRST POLYMER WITH A POLYFUNCTIONAL ORGANIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALCOHOLS, ACIDS, ACID ANHYDRIDES, HALIDES, AMINES KETONES, ISOCYANATES, EPOXIDES AND ARIZIDINYL COMPOUNDS.

Claim 2
